Abstract: A method and apparatus  (10)  for separating materials having different size densities is described. The apparatus includes a trough (12), a dispersing and conveying screw means  (40)  and a fluid distribution manifold (26).  The trough has upper and lower portions (12F and 12G)  with the lower portion forming a pool area.   The dispersing and conveying screw means has a conveying portion (46) and a dispersing portion (50). The conveying portion has flights (48) which move the first material  (152)  up the trough.   The dispersing portion has paddles  (52)  which disperse the mixture (150)  and convey the first material to the conveying portion.  The fluid distribution manifold supplies both water and air to the inside (12I) of the trough through fluid orifices (28).  In operation, the mixture is fed into the trough directly over the fluid orifices and the dispersing portion of the dispersing and conveying screw means.  As the mixture enters the trough, the mixture is dispersed and  forms an aqueous  suspension with the water.  The first material settles out of the aqueous suspension and is conveyed up the trough and out the upper discharge spout (14).  The second material (154) remains suspended in aqueous suspension and flows over the overflow weir and out the lower discharge spout.

Title: Video monitoring and conferencing system
Inventor: SCHWAB BARRY H
IPC: H04N7/10
Filed: 1996-04-04
Granted: 2007-02-06
Abstract: A PC-based system (220) for monitoring and storing representative images from video cameras (252, 254) may be utilized for security and other monitoring applications. Camera inputs from digital or analog sources are individu- ally and independently digitized and displayed at a first set of image sizes, sampling rates, and frame rates, and may be stored in digital form on various recording media at a sec- ond set of image sizes, sampling rates and frame rates, and these two sets of sizes and rates may or may not be identi- cal. Provisions are included for adding detection or alarm systems which will automatically alter image size, sam- pling rate and/or frame rate of an individual input source, or activate other physical responses. In addition to security system monitoring, further applications of the invention are disclosed for process monitoring in manufacturing environ- ments and also for applications in videoconferencing.

Title: Antenna having double-sided printed circuit board with colinear, alternating and opposing radiating elements and microstrip transmission lines
Inventor: BRENNAN MICHAEL L
IPC: H01Q21/10
Filed: 1998-01-21
Granted: 2003-08-05
Abstract: The present invention provides a microstrip collinear antenna having cable connector assembly means and a collinear microstrip printed circuit board means.  The cable connector assembly means responds to a radio signal, for providing a cable connector assembly radio signal.  The collinear microstrip printed circuit board means responds to the cable connector assembly radio signal, for providing a collinear microstrip printed circuit board radio signal.  The microstrip line collinear antenna is constructed with a number of one half .lambda. printed circuit board elements on both sides of a double-sided board.  These one half .lambda. sections are the radiators.  On the other side of the board opposite each radiator is a respective section of corresponding microstrip transmission lines to provide radio frequency power to each radiating element.  The microstrip line collinear antenna has the following advantages over the prior art antennas: it achieves shorter length due to close physical spacing of radiators, it maintains consistent pattern and impedance performance across the operating frequency range, it allows for accurate and consistent manufacturing through the use of advanced printed circuit board materials, allows for center feed design to achieve high-gain broadband operation, and it allows cost reduction with printed circuit board materials.

Abstract: Disclosed is an image processing apparatus for processing an image input from an image input device such as a digital camera. Upon reception of an image of an article from the image input device, this image processing apparatus discriminates the color and size of the article, and stores pieces of data indicating the discriminated color and size in correspondence with the image. When a color or size is designated as search data, the apparatus searches an image memory for images corresponding to the designated contents and displays them in the form of a list. When an article is imaged, pieces of feature data indicating the feature of the article are added and stored with respect to the image. When feature data is designated, the image of a desired article can be immediately searched out from many images.

Abstract: The present invention concerns a procedure for the production of PVC particl es with a narrow size distribution in the range 10-50 .mu.m, preferably 10-30 .mu.m, in which, in a first stage, a vinyl monomer o r a mixture of monomers is polymerised to form a polymer/oligomer seed particle in the range 1-10 .mu.m. In a second stage, another vinyl monomer or mixture of monomers is swelled into the polymer/oligomer seed particles and polymerisation takes place in such a way that they grow into polymer particles of the desired size. It is preferable to use aromatic vinyl monomers or acrylates as the monomer in the seed particle s. The seed particles in the first stage can be produced in a two-stage swelling process or by dispersion polymerisation.

Granted: 2002-12-10
Abstract: The present invention is generally related to mounting an integrated circuit chip on a printed circuit board, and more particularly to a socket that facilitates mounting and alignment of an integrated circuit chip on a printed circuit board.   Sockets for mounting electronic devices such as integrated circuit chips on a printed circuit board are known. The socket may be mounted to the printed circuit board, while the integrated circuit chip is snap-fitted into the socket. One advantage of this arrangement is that, unlike integrated circuit chips that are soldered directly on the printed circuit board, an integrated circuit chip that is mounted in a socket can be easily disconnected from the printed circuit board for testing and replacement. However, the relatively dense layout and small size of electrical contacts on same integrated circuit chips necessitates precise alignment both between the socket, and the printed
